Abstract

Based on conserved homologous amino-acid sequences of the Gq protein α subunit in arthropods, a pair of degenerate primers were designed to amplify the gene from the English grain aphid (Sitobion avenae), using reverse transcriptase polymerase chain reaction (RT-PCR) and (3′/5′)-rapid amplification of cDNA ends (3′/5′ RACE) techniques. A Gqα protein was obtained from the alate adult aphids. The open reading-frame was 1062 bp, encoding 352 amino-acid residues with a calculated molecular weight of 40.8 kDa. The cDNA sequence was deposited in GenBank with accession no. EF638906. The deduced amino-acid sequence of Gqα shared a high identity (≥82.17%) with reported Gqα from other insects and even vertebrates, and had the typical characteristics of Gqα protein. In order to explore the function of the Gqα gene, a eukaryotic expressional system (baculovirus expression vector system, BEVS) was constructed by TOPO and Gateway techniques. After the recombinant reaction occurring between pUC-Gqα and the Gateway-adapted baculovirus DNA from Autographa californica nuclear polyhedrosis virus (AcMNPV), the construct recombinant viruses containing V5-His6Gqα were transfected singly into the insect cell line of Tn-5B1-4. After collecting the infected cell, detection was conducted by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and western blotting. The result showed that the system comprising recombinant baculovirus and Tn could express Gqα protein successfully.
